Question

A neonate is displaying mottled skin, has a large fontanel and tongue, is lethargic, and is having difficulty feeding. The nurse recognizes that this is most suggestive of which disorder?

Answer 1

Correct Answers:

Hypothyroidism

Rationale :

🧠 Congenital hypothyroidism is a critical endocrine disorder that often presents subtly in the neonatal period. The signs described—mottled skin, macroglossia (large tongue), lethargy, and feeding difficulty—are hallmark features.

🧠 Early diagnosis is essential to prevent long-term complications such as developmental delay, mental retardation, and growth failure. This is why routine newborn screening includes a TSH and T4 panel to detect hypothyroidism before symptoms worsen.

🧠 Without sufficient thyroid hormone, the neonate exhibits slowed metabolism, hypotonia, and poor responsiveness, which can easily be mistaken for normal newborn behavior without vigilant assessment.

🧠 Treatment with levothyroxine must begin early to ensure optimal cognitive and physical development.

Answer 2

Correct Answers:

Absence

Rationale :

⚡ Absence seizures are most common in children aged 4–12 years and can often go unrecognized because they present as brief staring spells, typically lasting 5 to 10 seconds, without any convulsions or motor activity.

⚡ These events are due to abnormal electrical activity in the brain’s cortex, and the child typically has no memory of the event.

⚡ The child may pause mid-sentence, stare blankly, flutter their eyelids, and then resume activity as if nothing happened.

⚡ These seizures do not involve a postictal state, which differentiates them from other seizure types.

⚡ Diagnosis is confirmed by EEG showing generalized 3 Hz spike-and-wave discharges, and they are often effectively treated with ethosuximide or valproic acid.

Answer 3

Correct Answers:

Hydrocephalus

Rationale :

🧠 Hydrocephalus results from an imbalance between the production and absorption of cerebrospinal fluid (CSF), leading to ventricular dilation and increased intracranial pressure (ICP).

🧠 In infants, the open fontanels allow the head to expand, so early signs include rapid head circumference growth, bulging fontanels, distended scalp veins, vomiting, irritability, and poor feeding.

🧠 Early detection is vital, as progressive hydrocephalus can cause neurological damage.

🧠 Management typically involves surgical placement of a ventriculoperitoneal (VP) shunt, which redirects CSF from the ventricles to the peritoneum for absorption.

🧠 Nurses play a key role in monitoring for signs of shunt malfunction, such as vomiting, drowsiness, or seizure activity.

Answer 4

Correct Answers:

Secondary sex characteristic

Rationale :

👙 Tanner staging, also called Sexual Maturity Rating, is used to document and assess physical development during puberty based on external primary and secondary sex characteristics.

👙 These include breast development, genital development, and pubic hair distribution, and the stages range from I (prepubertal) to V (adult maturity).

👙 It provides a standard for clinicians to evaluate whether a child or adolescent is undergoing normal pubertal progression, as well as to identify delayed or precocious puberty.

👙 Tanner staging helps guide further diagnostic evaluation and counseling regarding growth expectations, fertility, and psychosocial readiness.

Answer 5

Correct Answers:

Short urethra in young girls

Rationale :

💧 The anatomical structure of a young girl's urinary system makes her more susceptible to UTIs. The urethra is short and close to the rectum, allowing bacteria—particularly E. coli—to ascend easily into the bladder.

💧 During toilet training or with improper wiping technique, contamination is more likely, especially if the child has poor hygiene habits.

💧 This risk is further exacerbated by holding urine, constipation, or bubble baths, all of which can irritate or provide a favorable environment for bacterial growth.

💧 Nurses educate parents on proper perineal hygiene, adequate hydration, and regular voiding habits to reduce UTI occurrence.

Answer 6

Correct Answers:

Increased motility results in impaired absorption of fluid and nutrients.

Rationale :

🚽 Diarrhea involves a combination of increased intestinal motility and reduced absorption time, leading to excessive fluid and electrolyte loss.

🚽 When the gut is hyperactive—due to infection, inflammation, or irritants—there is less time for nutrients and fluids to be absorbed, resulting in watery stools.

🚽 Prolonged diarrhea in children can lead to dehydration, metabolic acidosis, and nutritional deficiencies, especially in younger children who have smaller fluid reserves.

🚽 Management focuses on rehydration (oral or IV), restoring electrolyte balance, and addressing the underlying cause.

Answer 7

Correct Answers:

Because soft tissues are resilient in children, dislocations and sprains are less common than in adults.

Rationale :

🦴 In children, ligaments and tendons are stronger relative to the growing bones, so fractures are more common than sprains or dislocations.

🦴 Their bones are more pliable and porous, allowing for bending without complete breaks—hence injuries like greenstick fractures are typical.

🦴 The epiphyseal (growth) plates are also vulnerable to injury but allow for faster healing due to rich vascular supply and cellular activity.

🦴 This difference in tissue strength means that soft tissue injuries seen frequently in adults (e.g., ACL tears, rotator cuff injuries) are rarer in young children.

Answer 8

Correct Answers:

Monitor the child's intake and output.

Rationale :

🧪 Increased urination after trauma, particularly head trauma, may signal diabetes insipidus (DI) or cerebral salt-wasting syndrome

🧪 Both conditions result in excess fluid loss, leading to dehydration, hypernatremia or hyponatremia, and altered mental status if untreated

🧪 The nurse’s first and most crucial action is to monitor intake and output (I&O) closely to assess fluid balance

🧪 Tracking these trends informs further diagnostic testing and determines if intervention such as fluid replacement or vasopressin is needed

Answer 9

Correct Answers:

The adolescent is self-absorbed and self-centered and has sudden mood swings.

Rationale :

🧠 This behavior reflects the normal developmental process described in Erikson’s stage of Identity vs. Role Confusion

🧠 Adolescents often exhibit emotional lability, egocentrism, and conflicting desires for independence and support

🧠 Hormonal changes, peer pressure, and identity formation contribute to mood swings and self-focus, which are part of healthy maturation

🧠 These behaviors often concern adults but are not necessarily signs of pathology unless they interfere with function or persist severely

Answer 10

Correct Answers:

Warmth at site of pain

Rationale :

🔥 These signs strongly indicate local inflammation or infection, potentially osteomyelitis, a complication associated with orthopedic injuries and skeletal traction

🔥 Warmth, swelling, and localized pain—especially accompanied by fever—warrant immediate evaluation

🔥 Early recognition and intervention, including IV antibiotics and possible surgical drainage, are critical to prevent chronic bone infection and permanent disability

🔥 Nurses must monitor children in traction for both circulatory compromise and infection
